Identify polynomials in the following:

(i) f(x) = 4x³-x²-3x+7

(ii) g(x) = 2x³-3x²+-1

(iii) p(x) = x²-x+9

(iv) q(x) = 2x²-3x++2

(v) h(x) = x⁴-+x-1

(vi) f(x) = 2++4x

(i) f(x) = 4x³-x²-3x+7 is a polynomial.

(ii) g(x) = 2x³-3x²+-1 is not a polynomial as exponent of x in is not a positive integer.

(iii) p(x) = x²-x+9 is a polynomial as all the exponents are positive integer.

(iv) q(x) = 2x²-3x++2 is not a polynomial as the exponent of x in is not a positive integer.

(v) h(x) = x⁴-+x-1 is not a polynomial as the exponent of x in –x^3/2 is not a positive integer.

(vi) f(x) = 2++4x is not a polynomial as the exponent of x in is not a positive integer.
